[Spacewalk-list] unregister clients or remove pacakges from channel

[Ross]

Hello everyone

I have setup a software channel to push customized rpms to my desktop 
systems. Originally I created these rpms without a signature, but when I 
tried to push them to the clients, I got a gpg unsigned error. So I 
created the signature, attached it to the rpms, but when I try to push 
them to the channel, I get an oracle error (something about them not 
being unique). I can't find out how to delete/remove them from the 
channel, so I decided to delete the channel and start from scratch. But 
I can't delete the channel with computers subscribed to it, but I can't 
figure out how to un-register the clients. I would prefer to delete the 
packages from the channel, but failing this, then I would like to just 
re-create the channel. Can anybody help?

Thanks
